ARRANGEMENT OF FLIERS AND SPINDLES.

To all whom it may concern:

Be it known that 1, JOHN DEnMoND, of Paterson, in the county of Passiacand State of New Jersey, have invented a new and useful Improvement inthe Construction and Arrangement of Spindles and Fliers used inThrostle, Spinning, and Roving Machinery; and I do hereby declare thatthe following is a full and exact description of the construction andoperation of the same, reference being had to the accompanying drawings,forming part of this specification.

Figure 1, is a front elevation of the spindle bobbin and fliers asattached to a throstle or spinning machine. Fig. 2, is a verticalsection, the bobbin being removed. Fig. 3, is a plan of the movablecollar or guide for adjusting the tube.

Similar letters refer to the same parts in each of the figures.

My invention consists in bolting or in any other way firmly securing thespindle to the step or foot rail of the machine, and in having the tubeto which the flier is attached, with its inner diameter greater than thediameter of the spindle, so that it revolves outside the spindleconcentric with it. The spindle and tube are entirely independent ofeach other and do not touch each other while working. This arrangementwill obviate the inconvenience generally found to arise from thevibration of the spindle when it revolves with the fliers attached, andwill preserve an uniform drag on the threads while it is being twisted.The lower end of the tube rests in a step bearing attached to the frameof the machine and is kept in a vertical position by means of a guidenear its upper end. This guide and also the step bearing are capable ofadjustment should the tube deviate from a vertical position.

To enable others skilled in the art to make and use my invention I willnow describe its construction and operation.

A, is the spindle On the upper end of which the bobbin a, is placed asseen in Fig. 1.

B, is the step by which the spindle is carried.

C, C, are guides attached to the step on its lower side, for the purposeof preserve ing the vertical position of the spindles while being raisedand depressed as re quired in the action of the machine. D, is theflier; E, the tube; F, a step bearing attached to the frame of themachine in which the tube works; G, a movable collar or guide attachedto the frame for keeping the tube in a vertical position. H, is an armattached to the frame of the machine which carries the movable collar orguide G which is fitted to it and secured by screw bolts. This arm has aslot in it, I, is a bolt passing through the slot in the arm, H, for thepurpose of securing it to the frame of the machine. The slot allows thearm to be moved in any required direction to adjust the spindle in avertical position.

The step bearing F is carried by an arm,

K, and secured to the frame by a bolt L and is capable of the sameadjustment as the arm, H, already described.

The operation of my machine is as fol lows. The thread is broughtthrough the eye of the flier to the bobbin which is stationary on thespindle, a rotary motion is communicatedto the flier by means of anendless band working on a pulley on the tube E. The revolution of theflier gives the required twist to the thread and at the same time windsit on the bobbin. When the flier has been running for some time it isobvious that it will wear loose in its guide G, and lose its precisevertical position or get out of plumb; the movable collar G may withlittle trouble, be taken out and a new one substituted in the arm Hwhich may be again adjusted in the manner described.

hat I claim as my invention and desire to secure by Letters Patent isThe manner of suspending the flier separate from the spindle by theflier being connected to, and forming a part of the tube, E, the lowerend. of which revolvesin a socket bearing, allowing the spindle of thebobbin to pass and move through it without touching it, so that howevergreat the speed of the flier may be it will be prevented from vibratingthe spindle.
